Troubleshooting
If you are unfamiliar with this product, please pay close attention to the
requirements for installation. Failure to do so can result in permanent damage
to the pickup.
Installation by a qualified professional is strongly recommended.

Installation
1. Measure the opening of the bass side wing slot on the bridge with a vernier
caliper. The opening should be between .060” and .090” (1.5mm and 2.3mm) for
proper fit.
If the wing slot opening of the cello measures more than .090” (2.3mm), the leg
facing the pickup must be shimmed. For that purpose, we have provided a strip
of wooden shim material that can be easily cut with scissors, stacked and glued
to produce a shim of any required thickness.

2. Slide the transducer into the bass wing slot as shown. Make certain that the
sensing element is in contact with the wing face and that the spring (made of
tempered beryllium copper) is in contact with the corresponding “leg” face of
the bridge.
Note: For best performance, the wing
slot opening should be .070” (1.8mm).
3. For permanent installation, use any
appropriate wood adhesive to bond the
shims to the face of the bass side wing. As
a result, the shims will be located between
the transducer’s sensing element and the
bass side wing.
Note: The performance of the C-100 is
affected by the amount of contact area
between its sensing element and the wing
face of the bridge. Accordingly, the performance may be adversely affected if the wing
face has been stylized or carved in any way.

4. Once the transducer is properly inserted into the
bridge, the next step is to mount the adhesive-backed
jack mount to the back side of the tailpiece. First, peel
off the release film from the holder and then press the
holder firmly in place below the fine tuning machines
of the tailpiece. Position the holder so that the jack,
when slipped into the holder, will be at a right angle
(90°) to the tailpiece.
5. Insert the jack into the holder and snap shut. Since the
wire is somewhat microphonic, it should not be allowed
to lie on the face of the instrument.

Fine Tuning
Once the C-100 is properly mounted, plug the instrument into an amplifier and
play at a low volume. Carefully shift the position of the C-100 within the slot and
listen for the best location.
Note: If installation is to be permanent, a small drop of cyanoacrylate adhesive
on the spring side (lower face) of the transducer can be used.

Plugging In
An impedance matching preamp is recommended, but not required. This will
help realize the full frequency response potential of the pickup and allow for
cable runs longer than 10 feet without signal deterioration. Use a high quality,
low capacitance ¼” shielded instrument cable. This will ensure minimal tone
coloration and hum.
